摘要

本文叙述了利用同轴结构Xe

离子激光器的UVλ=365nm激光作为激发光源的激光感生荧光(LIF)实验系统

对医用X射线ZnCdS:Ag荧光屏的发光性能进行了研究.LIF方法能方便而高灵敏地同时测得荧光光谱与寿命

和传统的紫外灯激发及X射线激发的结果一致

可以完全避免X射线对人体的有害辐射.

Abstract

The experimental system of laser-induced fluorescence (LIF)which uses the UV (λ=365nm) light of pulsed Xe

ion laser with coaxial structure as the exciting source is described. The UV output characteristic of pulsed Xe

ion laser was studied. It is the first time to use such a system to investigate the luminescence performance of ZnCdS:Ag fluorescent screen for medical X-ray. The LIF technique

which has very high sensitivity

can be easily used to measure the fluorescent spectrum and lifetime simultaneously. Experimental results are consistent with those obtained by using other methods (e.g. using UV lamp or X-ray as exciting source). The LIF technique has the advantage of avoiding the damage of X-ray radiation to human body.
